1.Structure of  Ball Valve Description

Threaded ball valve is closed is a ball, ball around the center line of the body as a rotation to achieve a kind of open and close the valve.
Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium. Two type ball valve, three type ball valve, is widely used in recent years a new type of valve, the valve average installation. And ball valve is a kind of ball valves, threaded pipe connection is screwed connection, and flanged ball valves, welded ball valve, etc.

2. Main Features of the Ball Valve

• Small flow resistance;

•  Simple structure

• Small volume, light weigh

• Small volume, light weigh

•  Easy to operate, open and close quickly, facilitate remote contro

• Easy maintenance, sealing ring, which generally remove easy to change

• Full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through does not cause the valve sealing surface erosion.

4.FAQ

1. What's are the characteristics of ball valve?

The distinct feature of a ball valve is the sealing surfaces between the gate and seats are planar, so ball valves are often used when a straight-line flow of fluid and minimum restriction is desired. The ball valve faces can form a wedge shape or they can be parallel. 

2. What is the work principle of ball valve

 The ball valve faces can form a wedge shape or they can be parallel. Ball valves are primarily used to permit or prevent the flow of liquids, but typical ball valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, ball valves are often used in the petroleum industry. 

3.  What is the structure?

Bonnets provide leakproof closure for the valve body. Ball valves may have a screw-in, union, or bolted bonnet. Screw-in bonnet is the simplest, offering a durable, pressure-tight seal. Union bonnet is suitable for applications requiring frequent inspection and cleaning. It also gives the body added strength. Bolted bonnet is used for larger valves and higher pressure applications.

Q:How to suppress the valve?
Upstairs is right... But look at the situation, there are some valve flange is 16 pressure, but the body can only play 10 pressure, there are cases.. Such as knives, valves and other ventilation valve
Q:How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?
Which standard does the wall thickness refer to? ASME B16.34?Design and calculation depends on what standard you chooseOr have you found the standard yourself and read it yourself?You choose what standards, design parameters reference, interpolation or fitting, how to fit, are their own sayI wrote a excel series of valve calculations, it does not take long to writeFor long-term useIn order to improve efficiencyOr write your own database program is better
Q:What does the valve specification "3/4CL150" mean?
Size: DN20 pressure rating: 150 pounds American Standard
Q:What is the BV valve?
It should be American Copeland company, BV series valves;
Q:What do the D373W and D373H of the valve mean?
Upstairs said yes, I have factory production, this butterfly valve.
Q:Valve pressure test
Strength test is nominal pressure of 1.5 times, the test time is 5min, the test time, the valve body is not broken, no deformation, the valve is not leaking water, the pressure gauge does not drop to qualified. After the strength test has passed, the tightness test is carried out. The tightness test pressure is equal to the nominal pressure. The valve does not leak in the test time, and the pressure gauge does not drop to be qualified.
Q:Dalian hi Max Valve Co., Ltd.
I have to do the technical sales colleagues is high inside out now before the inside sales revenue is also good about one hundred thousand a year as sales of a great degree of luck the.I do not know what the specific circumstances, what age, in this line for several years, there is the opportunity to communicate with the landlord and make progress together.
Q:Is the valve clockwise?
Tap water valve is generally divided into two kinds, one is ball valve, and the other is gate valve. The ball valve wrench is vertical when the water pipe is closed, is a twist or reverse, 90 degrees wrench and water pipe is open when the direction; valve handwheel clockwise turn off, anti clockwise turn is open. Valve in the application should not be twisted too tight, so as to avoid the thread buckle, spool off. Ball valve applications save effort and durability.
Q:Heating pipes, in addition to the living room,
You just put the living room off the water inlet valve, open the drainage valve with backwater top a try
Q:What does the "PN" mark on the valve mean?
The valve will usually be marked with "DN.PN." these two signs,DN refers to the valve path, and PN refers to the pressure levelFor example: DN25, PN16Refers to the valve diameter of 25mm valve, the pressure is 16 kg (1.6Mpa)
